AIR-COOLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 556,811, dated March24, 1896.

Application filed July 15 18 9 5 To all whom it may concern.-

Be it known that I, FREDERICK W. DOLD, of Kansas City, Jackson county,Missouri, have invented certain new and useful Improvements inRefrigerating Apparatus, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming a part thereof.

My invention relates to refrigerating apparatus, and has for its objectto produce brinereceptacles having a comparatively extendedcooling-surface and of such peculiar configuration that the accumulationof frost upon the bottom and sides of the receptacles is prevented.

A further object is to provide a receptacle from which, aftercirculating properly, the warmer brine may readily escape, being forcedout of the receptacle by the continuous supply of brine at a lowertemperature.

A still further object is to provide means whereby superimposedbrine-receptacles may be easily and quickly adjusted toward or from eachother.

With these objects in view the invention consists in certain uove landpeculiar features of construction and combinations of parts, as will behereinafter described and claimed.

In order that the invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-Figure 1 represents in perspective a brinereceptacle embodying myinvention. Fig. 2 represents a pair of said receptacles superimposedwith relation to each other and adjustably connected.

In the said drawings, 1 designates a brinereceptacle, which consists ofthe approximately V-shaped bottom 2, the sides 3 flaring upwardly fromthe upper or side margins of the bottom, the upwardly-converging flangesat, which connect at their lower ends with the upper ends of the sides3, and the ends 5, which in contour correspond, preferably, to thecross-section of the pan.

6 designates a pair of guide boards or plates, which converge downwardlyfrom the upper ends of the flanges 4, extending preferably nearlyparallel with the sides 3 of the pan and having their lower edges in aplane below the longitudinal series of holes or aper- Serial No.556,019. (No model.)

tures 7 of the flanges 4. I prefer to construct this pan, with theexception of the guide boards or plates 6, of sheet metal, such asgalvanized iron, though it is to be understood, of course, that anymaterial or combinations of materials may be employed without departingfrom the spirit of the invention. Said receptable is preferablysupported by a number of pendent hangers S secured at their lower endsexternally to the sides of the receptacle, as shown at 9, and at theirupper ends adj ustably by bolts 8 and nuts 8 tothe hangers 8, secured toany suitable supporting-framework, as at 10. In practice two or more ofthese pans will preferably be arranged in vertical alignment, so as toutilize space and receive the full benefit of the flowing brine beforeit escapes. To secure this relation between said receptacles, I securependently to the upper receptacle or to the hangers 8 of the same, inthe manner shown, the hangers 11, provided at their lower ends withoutwardly-projecting shoulders 12, and secure to the receptacle belowthe upwardlyprojecting hangers 13, provided at their upper ends withoutwardly-projecting shoulders 14, similar to the shoulders 12, andextending through aligned apertures in said shoulders, the bolts 15,which may be adjusted longitudinally so as to move the lower receptaclenearer to or farther from the upper receptacle by the nuts 16, whichrest upon the shoulders 12. The upper receptacle, of course, is arrangedvertically below the brine-supply pipes 17, which may be supported andarranged in any suitable or preferred manner, through which the brine atthe required temperature is forced, in the usual or any preferredmanner, into the said upper receptacle.

The brine naturally, after it leaves the rerises upwardly and outwardlyin the direction indicated by the featherless arrows under the action ofthe wedge-like entrance of that at a lower temperature, as indicated byfeathered arrows, upwardly to the holes or apertures 7, from which itescapes in constant streams and flows down the sides and V- shapedbottom of the pan until the apex thereof is reached. From the apex ofthe bottom it descends in a continuous stream or volume into the panbelow, wherein the circulation before traced is repeated. The brine alsoescapes from said receptacle through the aperture 7 in the manner aboveexplained, and may then be disposed of in the usual or customary manner.

Thus it will be seen that a continuous stream of cold brine is suppliedto said-receptacles and may be retained in the refrigerating-apartmentfor any length of time desired, this being determined by the number andcapacity of the receptacles employed in series, and as said brineapproaches an undesirably high temperature it is conveyed away. It willalso be apparent owing to the peculiar configuration of the pans incross-section, that the escaping brine flows over the entire side andbottom surface thereof and, preventing the accumulation of frost on saidparts, utilizes the comparatively extended refrigerating-surface on eachreceptacle, so that the radiation of the cold air from said recep taclesis more complete and thorough than could be obtained if frost werepermitted to accumulate on the bottoms of said receptacles, whichaccumulation of frost would tend to raise the temperature in less timethan would be required by direct contact of swiftlymoving brine with thesides and bottom of the receptacle. If it be desired to increase thereceptacle capacity of the refrigeratingapartment, or for any otherreason, the superimposed receptacles, by properly manipulating the nuts16, may be brought nearer together, or may be moved farther apart, theadjustment being limited, of course, by the length of the bolts 15.

From the above description it will be apparent that I have producedeffective refrigerating apparatus which is extremely simple andinexpensive of manufacture, and strong and durable of construction.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a refrigerating apparatus, a brine-receptacle, approximatelyV-shaped in crosssection and provided at its upper margins withupwardly-proj ectin g perforated flanges, and at the upper margins ofsaid flanges with downwardly converging guide boards or plates, arrangedsubstantially as and for the purpose set forth.

2. In a refrigerating apparatus, a brine-receptacle, comprising anapproximately V- shaped bottom, sides upwardly diverging from the upperor side margins of the bottom, upwardly-converging perforated flanges atthe upper ends of the sides, guide boards or plates convergingdownwardly from the upper ends of said flanges, and ends engaging theopposite ends of the V-shaped bottom, the sides, the perforated flanges,and said guideboards, substantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
